Does the Fetch Annotations for Last Page Read only work for Mobi files? I have searched my library for those that contain Last Page Read in the Description comments and found they are MOBI files for which my Kindle had the MOBI file. But if I am reading an AZW file on the Kindle, there is no Last Page Read notation in my Calibre library for that book, even though I have Fetched Annotations. Could somebody explain when Fetch Annotations works and when it doesn't?

Someone suggested using book uuid as the ASIN field and set cdetype to EBOK to allow Amazon furthest read tracking to work with Calibre Mobi files. Where in the interface do you have the chance to set those?
